Category: Core: libscim Group: 1.4.x Status: Open Resolution: None Priority: 5 Private: No Submitted By: akb825 (akb825) Assigned to: Nobody/Anonymous (nobody) Summary: Segfault when loading SCIM module in some applications Initial Comment: There are a couple of applications that encounter a segfault when loading a SCIM module immediately on startup. The original application I have been having problems with is bsnes. (http://byuu.org/bsnes/) When trying to find a similar application (using the same underlying libraries) that exhibits this behavior I discovered hedgewars (http://www.hedgewars.org/) which also segfaults in the same way. To reproduce, simply install either application and attempt to launch it. I am running Debian Testing with GNOME, which has SCIM version 1.4.9-3. The SCIM packages I have installed are scim scim-anthy, scim-bridge-agent, scim-bridge-client-gtk, scim-gtk2-immodule, scim-qtimm, and scim-uim. I am using US English as my system language, and the keyboard layout is set to US English. Removing SCIM resolves the segfault. Both bsnes and hedgewars use QT4. Other QT applications run fine, but one similarity between these two applications is that they also use SDL. Since both QT and SDL provide input functionality, I'm wondering if those are somehow conflicting when SCIM is initialized. I am currently using the default GTK theme for QT, which routes all of its UI elements through GTK. You can specify different themes, which aren't GTK based, for each application with the "-style" command line argument, such as "-style motif". Passing the "-style motif" command line argument works around the issue and prevents the segfault in both bsnes and hedgewars. I have looked through the source code for bsnes, and immediately after main it creates a QApplication instance to initialize QT, where it then crashes, so it doesn't appear to be doing anything abnormal during initialization. Here is a stack backtrace for the segfault when attempting to launch bsnes: #0 0x00007fffe4a14843 in ?? () from /usr/lib/libltdl.so.7 #1 0x00007fffe4a15248 in ??

Do you still have this problem with newer version of scim? Thanks. ---------------------------------------------------------------------- Comment By: Skillspace Projects (skillspace) Date: 2010-10-31 19:10 Message: Forgot to mention below: I have installed *only* scim-1.4.9, no other scim-related software. Using default X11 frontend that comes with scim. KDE 4.2.4, Slackware 13.0, and again Firefox 3.6.10. ---------------------------------------------------------------------- Comment By: Skillspace Projects (skillspace) Date: 2010-10-31 19:05 Message: I also have a segfault problem with scim-1.4.9 and Firefox 3.6.10. SCIM-RELATED APPLICATION BEHAVIOR NOTES (only happened since installing SCIM, today): 1) There is no problem with using SCIM. 2) Browser and related windows often freeze (or are slow to load) until I right-click the SCIM icon and select "Exit." 3) The icon disappears and immediately reappears. (Error messages indicate the "exit" message is not actually accepted, but this seems to allow the browser or whatever related window to finish loading. 4) Every time I want a new window to finish loading (Session Restore, Xmarks Sync, Firefox Preferences, Exceptions (to cookie-handling), etc, etc) I must repeat #2 above!
